9 Claims. (Cl. 189-69) The present invention relates broadly to operatable closure means for an opening, and in its specific phases to a special form of operating mechanism for a hinged window or ventilator apparatus.

Several different types of crank-actuated operating means have been devised for windows and ventilators of buildings and movable compartments, such as house trailers, particularly hinged ventilators used in the roof and small hinged windows used in the side walls near the roof of the latter. Such operating means in general have not tightly closed the hinged windows or ventilators at the edge remote from their hinge mountings, allowing entrance of driving rain, and outside air in addition to the escape of heat in winter. It was a recognition of these difficulties and shortcomings of the prior art which lead to the conception and development of the present invention.

Accordingly among the objects of the present invention is the provision of a new and improved operating means which will insure tight closing of a window or ventilator at the edge thereof remote from its hinge mounting means, thus making it possible to have a tight seal entirely around the window or ventilator.

Another object of the present invention is to provide a swingable arm operable by means of a hand crank, and a link connecting said arm with the hinged window sash or ventilator to push this sash or ventilator open when the crank is turned in one direction and to pull it shut when said crank is turned in the other direction. These elements are not uncommon, but the present invention is designed to provide a new and improved construction and relation whereby the link acts as a lever during the final closing of the sash or ventilator to force the edge thereof remote from the hinged edge tightly in against the frame.

A further object of the invention is to provide a novel construction which will be simple and inexpensive yet efficient and reliable.

Still further objects and advantages of the present invention will appear as the description of the invention proceeds.

To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain means for carrying out the invention, such disclosed means illustrating, however, but one of various ways in which the principle of the invention may be used.

In the anneXed drawings:

Figure 1 is an inner side elevation of a house trailer window embodying the invention.

Figure 2 is an enlarged vertical sectional view on line 22 of Figure 1, looking in the direction of the arrows and showing the sash closed.

Figure 3 is an end elevation, partly broken away and in section, showing the sash partly opened.

Figure 4 is a fragmentary edge view of the push and pull link, and a portion of the swingable arm connected to said link.

Figure 5 is a perspective view of a channel bar, shown in the assemblies of Figures 2 and 3, which in use is secured to the sash and pivotally connected to the link.

The invention will be described in connection with a window and its sash, but the term sash is to be interpreted as comprehending not only an actual sash but any 2,699,232 Patented Jan. 11, 1955 "ice swingable closure means which might be used in place thereof to provide a closure for an openable passageway such as in a ventilator instead of an actual window. Also, the term window frame is to be considered as comprehending a frame of an openable passageway closure member such as a ventilator as well as a frame for a window.

A metal window frame is shown at 6, said frame having an outer peripheral attaching flange 7, an inner peripheral flange 8 and a continuous side wall 9 connecting said flanges 7 and 8. The flanges 7 and 8 for most uses are substantially parallel, and the side wall 9 will ordinarily space flange 8 inwardly from flange 7.

A sash 10, for a flush assembly, is closable against an inner offset portion of the flange 7 of the frame 6, Figures 2 and 3, and is connected at its upper edge with said flange by a hinge 11. The sash shown comprises a metal frame 12, a pane 13, and a rubber gasket 14 connecting said frame and pane, said gasket ordinarily being of general H-shape in cross-section to provide channels snugly receiving the adjacent edge portions of said frame 12 and pane 13. The frame 12 is provided with a suitable gasket 15 at its inner face for tight sealing contact with the flange 7.

Centrally between the ends of the sash frame 12, and in front of bar 20, a vertical channel bar 16 is provided at the inner side of said sash frame. The side flanges of this channel bar 16, Figure 5, are denoted at 17 and the flange-connecting portion at 18. This: portion 18 preferably lies against the inner side of the pane 13, Figure 2, and its ends 19 extend into the channel of the gasket 14 which receives the edges of said pane. The channel bar 16 is thus secured to the sash frame 12 in a simple and convenient manner.

A central flat bar 20 vertically spans the frame 6 in opposed relation with the channel bar 16 and is secured by rivets or the like 21 to the flange 8 of said frame 6. Between its ends, this bar 20 is formed with a slot 22.

A casing 23 is secured with screws 24 to the bar 20 and contains a worm wheel 25, which is preferably segmental as shown, and worm gear 26, said worm gear having a shaft 27 to which an operating crank 28 is secured. The worm wheel 25 is provided with an arm 29 which extends through the slot 22 of the bar 20, said arm occupying an upstanding vertical position between the side flanges 17 of the channel bar 16 when the sash 10 occupies its closed position, as seen in Figure 2. Also disposed between these flanges 17 is a push-and-pull link 36 which occupies a vertical position when the sash is in closed position. The lower end of the link 30 is connected with at least one of the flanges 17 of the channel bar 16 by a pivot 31. Near its upper end, the link 30 is connected with the arm 29 by a pivot 32. Thus, swinging of the arm 29 by turnmg the crank 28, will cause the link 30 to push or pull upon the channel bar 16, thereby opening or closing the sash 10 as required.

At its upper end 33, the link 30 projects above the pivot 32 to lie against an outwardly facing portion of the frame 6 as shown in Figure 2 when the sash 10 occupies its closed position. In the present showing, this outwardly facing portion is an abutment plate 34 secured to the outer side of the flange 8 of the frame 6. The link end 33 comes into contact with the abutment plate 34 when the sash 10 is almost closed. Consequently, the final sash-closing movement of the arm 29 (in the direction of the arrow on pivot 32 in Figure2) will swing the link 30 about said abutment plate 34 as a fulcrum, causing the lower end of said link to move in the direction of the arrow on pivot 31. Thus, the link 30 becomes a lever and forcibly pries the lower edge of the sash 10 tightly in against the flange 7 of the frame 6. This effectively overcomes the lack of tight closing at the lower edge of the sash as in prior constructions.

From the foregoing, it will be seen that novel and advantageous construction of the closable assembly has been provided for attaining the desired ends which particularly involve the tight closing of the assembly, and while preferences have been disclosed, it is to be understood that variations may be made within the scope and principles of the invention as set forth. Also, it is to be understood that such terms as inner, outer, upper, lower, and vertical as herein used, are illustrative rather than limiting.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the apparatus herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:
